摘要：
Using the process e-gamma--> W(nu) we study the WW-gamma vertex in e+e- collisions with polarized beams at a future 500 GeV collider. The equivalent photon approximation and its accuracy are discussed for the case of polarized electron beams. The resulting photon spectrum is then used to compute the total cross section as well as various differential distributions for the process e+e- -->e+W-(nu). Special emphasis is put on the effects of using polarized electron beams and their influence on the sensitivity to anomalous couplings.
